Academics

1) For an aldol reaction, the key step is the attack on the partially positive carbonyl carbon by a nucleophile. Rank benzaldehydes by their reactivity in an aldol reaction.

2) why doesn't this aldol reaction make multiple major products even though there are two carbonyl compounds in the reaction?

3) why do you only obtain the trans isomer as the product for these reactions?
